returns a list of L<http header|Archive::Har::Entry::Header> objects

=head2 cookies

returns a list of L<http cookie|Archive::Har::Entry::Cookie> objects

=head2 query_string

returns a list of the individual L<objects|Archive::Har::Entry::Request::QueryString> in the query string

=head2 post_data

returns the L<post data|Archive::Har::Entry::Request::PostData> object.  This may return undef if the postData is not defined.

=head2 headers_size

returns the total number of bytes in the http request up to and including the double CRLF before the start of the request body

=head2 body_size

returns the total number of bytes in the http request body

=head2 comment

returns the comment about the Request
